Safety Information
Explanation of Safety Messages
Precautionary statements (“DANGER,” “WARNING”
and “CAUTION”), followed by specific instructions,
are found in this manual and on machine decals. These
precautions are intended for the personal safety of the
operator, user, servicer and those maintaining the
machine.
Important Safety Instructions
WARNING
To reduce the risk of fire, electric shock,
serious injury or death to persons when
using your washer, follow these basic
precautions:
W023
DANGER
DANGER indicates the presence of a
hazard that will cause severe personal
injury, death, or substantial property
damage if the danger is ignored.
WARNING
WARNING indicates the presence of a
hazard that can cause severe personal
injury, death, or substantial property
damage if the warning is ignored.
CAUTION
CAUTION indicates the presence of a
hazard that will or can cause minor
personal injury or property damage if the
caution is ignored.
Additional precautionary statements (“IMPORTANT”
and “NOTE”) are followed by specific instructions.
IMPORTANT: The word “IMPORTANT” is used
to inform the reader of specific procedures where
minor machine damage will occur if the procedure
is not followed.
1. Read all instructions before using the washer.
2. Refer to the GROUNDING INSTRUCTIONS in
the INSTALLATION Manual for the proper
grounding of the washer.
3. Do not wash textiles that have been previously
cleaned in, washed in, soaked in, or spotted with
gasoline, kerosene, waxes, cooking oils, drycleaning solvents, or other flammable or
explosive substances as they give off vapors that
could ignite or explode.
4. Do not add gasoline, dry-cleaning solvents, or
other flammable or explosive substances to the
wash water. These substances give off vapors that
could ignite or explode.
5. Under certain conditions, hydrogen gas may be
produced in a hot water system that has not been
used for two weeks or more. HYDROGEN GAS
IS EXPLOSIVE. If the hot water system has not
been used for such a period, before using a
washing machine or combination washer-dryer,
turn on all hot water faucets and let the water
flow from each for several minutes. This will
release any accumulated hydrogen gas. The gas is
flammable, do not smoke or use an open flame
during this time.
6. Do not allow children to play on or in the washer.
Close supervision of children is necessary when
the washer is used near children. This is a safety
rule for all appliances.
NOTE: The word “NOTE” is used to communicate
installation, operation, maintenance or servicing
information that is important but not hazard
related.

7. Before the washer is removed from service or
discarded, remove the door to the washing
compartment.
20. If the supply cord is damaged, it must be replaced
by a special cord or assembly available from the
manufacturer or its service agent.
8. Do not reach into the washer if the wash drum is
moving.
21. Be sure water connections have a shut-off valve
and that fill hose connections are tight. CLOSE
the shut-off valves at the end of each wash day.
9. Do not install or store the washer where it will be
exposed to water and/or weather.
10. Do not tamper with the controls.
11. Do not repair or replace any part of the washer, or
attempt any servicing unless specifically
recommended in the user-maintenance
instructions or in published user-repair
instructions that the user understands and has the
skills to carry out.
12. To reduce the risk of an electric shock or fire, DO
NOT use an extension cord or an adapter to
connect the washer to the electrical power source.
13. Use washer only for its intended purpose,
washing textiles.
14. Never wash machine parts or automotive parts in
the machine. This could result in serious damabe
to the basket.
15. ALWAYS disconnect the washer from electrical
supply before attempting any service. Disconnect
the power cord by grasping the plug, not the cord.
16. Install the washer according to the
INSTALLATION INSTRUCTIONS. All
connections for water, drain, electrical power and
grounding must comply with local codes and be
made by licensed personnel when required.
17. To reduce the risk of fire, textiles which have
traces of any flammable substances such as
vegetable oil, cooking oil, machine oil,
flammable chemicals, thinner, etc. or anything
containing wax or chemicals such as in mops and
cleaning cloths, must not be put into the washer.
These flammable substances may cause the
fabric to catch on fire by itself.
22. Loading door MUST BE CLOSED any time the
washer is to fill, tumble or spin. DO NOT
bypass the loading door switch by permitting the
washer to operate with the loading door open.
23. Always read and follow manufacturer’s

(preferably in a locked cabinet).
24. Always follow the fabric care instructions
supplied by the textile manufacturer.
25. Never operate the washer with any guards and/or
panels removed.
26. DO NOT operate the washer with missing or
broken parts.
27. DO NOT bypass any safety devices.
28. Failure to install, maintain and/or operate this
washer according to the manufacturer’s
instructions may result in conditions which can
produce bodily injury and/or property damage.
NOTE: The WARNINGS and IMPORTANT
SAFETY INSTRUCTIONS appearing in this
manual are not meant to cover all possible
conditions and situations that may occur. Common
sense, caution and care must be exercised when
installing, maintaining or operating the washer.
Any problems or conditions not understood should be
reported to the dealer, distributor, service agent or the

Operation
Power Failure Recovery
Error Display Indications
If a cycle is in progress and the power fails, cycle
status is saved in memory (for a minimum of six years)
without power being applied.
An error is recoverable if normal machine function can
resume without having to shut off power to the
machine. See below for recoverable errors.
If power resumes within 1 minute and 30 seconds, the
previously active cycle will continue without having to
press START.
If the control was in a fill cycle step and if the preprogrammed pressure switch is not satisfied, the
control will start the Fill/Tumble step from the
beginning.
If the control was in an intermediate extract step, the
rest of the extract step is lost and the control will
resume in the next cycle step. However, if in the
intermediate extract step prior to the final extract or in
the final extract, the control will resume the cycle from
the beginning of the previous Drain/Tumble step.
If power resumes anytime after 1 minute and
30 seconds and less than or equal to the time
programmed by the owner for the Power Fail Reset,
or if the Power Fail Reset feature is disabled, the
control will enter into the START Mode at the
beginning of the cycle step where the power failed.
If power resumes anytime after the time programmed
by the owner, the control will revert to the READY
Mode. The Power Failure Recovery feature may be
modified by using the Micro-Wand IIIE.

one minute. After one minute, if door still isn’t
locked, computer stops trying. If any key is
pressed or door is opened, the display will
change back to the normal START Mode display.
In DOOR UNLOCK Mode, computer displays
“E:dL” after 10 seconds of trying to unlock door
for one minute. If any key is pressed, display
reverts back to Door Unlock display. Computer
again attempts to unlock door. Moving the door
handle will usually free the door lock and allow it
to be unlocked.
If door is sensed as unlocked during a cycle,
computer will display “E:dL” and terminate the
cycle. Computer must be powered down at this
point.

Care of Stainless Steel
●
Remove dirt and grease with detergent and water.
Thoroughly rinse and dry after washing.
●
Avoid contact with dissimilar metals to prevent
galvanic corrosion when salty or acidic solutions
are present.
●
Do not allow salty or acidic solutions to
evaporate and dry on stainless steel. Wipe clean
of any residues.
●
Rub in the direction of the polish lines or “grain”
of the stainless steel to avoid scratch marks when
using abrasive cleaners. Use stainless steel wool
or soft, non-metal bristle brushes. Do not use
ordinary steel wool or steel brushes.
●
If the stainless steel appears to be rusting, the
source of the rust may actually be an iron or steel
part not made of stainless steel, such as a nail or
screw. Tip: Paint all carbon steel parts with a
heavy protective coating. Stainless steel fasteners
should be used whenever possible.
F232136
●
Remove discoloration or heat tint from
overheating by scouring with a powder or by
employing special chemical solutions.
●
Do not leave sanitizers or sterilizing solutions on
stainless steel equipment for prolonged periods
of time.
●
When an external chemical supply is used, ensure
no siphoning of chemicals occur when the
washer-extractor is not in use. Highly
concentrated chemicals can cause severe damage
to stainless steel and other components with the
machine. Damage of this kind is not covered by
the manufacturer’s warranty. Locate the pump
below the washer-extractor’s injection point to
prevent siphoning of chemicals into the machine.
